Duration: 45 minutes
Steps: 26 Steps
Hello, Galaxy SM-G998B/DS adventurers! Ready to tackle the project ahead? Let’s get going. If you run into a snag, remember: you can always schedule a repair. You’ve got this!
Hey there! Ready to give your Samsung Galaxy S21 Ultra a little TLC? Let’s dive in and swap out that charging board. Just a heads up, if you forget to replace the adhesive seals, your device should work fine, but it might lose its water resistance. Don’t sweat it though, just grab some replacement adhesive to stick everything back together. Need a hand? You can always schedule a repair with Salvation Repair!
Step 1
Make sure to unplug and power off your phone before getting started.
You can also use a hair dryer, heat gun, or hot plate, just remember, don’t overdo it with the heat! The display and internal battery don’t handle heat well.
– Alright folks, time to get our heat on! Grab an iOpener and let it chill on the back cover for at least 3 minutes. This’ll help us free up those sticky adhesives and make our work a breeze! If you need help, you can always schedule a repair.
Step 2
Got a back cover that’s shattered like a dropped disco ball? Try sticking some clear packing tape over it—your suction cup might grip better. Or skip the fuss and use some super sticky tape instead of the suction cup. If none of that sticks (literally), a dab of superglue on the suction cup can do the job!
Struggling to make a gap appear? Give it some more heat to melt that stubborn adhesive. Just keep calm and follow the iOpener instructions to keep things cool and avoid overdoing it!
– Get yourself a suction handle and securely attach it to the bottom edge of the back cover, as close to the edge as you can.
– Use the suction handle to lift up the back cover, creating a small gap between the back cover and the frame.
– Grab an opening pick and slide it into the gap you just made.
– Gently slide the opening pick to the lower left corner to cut through the adhesive.
– Keep the opening pick in place to make sure the adhesive doesn’t seal back up.

Step 3
– Pop in another opening pick along the bottom edge of your phone—it’s like having a buddy for your tech adventure!
– Give that pick a little glide down to the bottom right corner and slice through that pesky adhesive.
– Keep those picks in place like a pro to make sure the adhesive doesn’t sneak back together.
Step 4
Whoops! If the adhesive is being a tough cookie to cut, it’s probably gets chilly. Warm things up with your iOpener for about 2-3 minutes, and it’ll be ready to roll!
– Pop in a third opening pick at the bottom right corner of your phone.
– Gently slide that pick along the right edge of your phone to cut through the adhesive like a pro.
– Keep the opening pick wedged in the top right corner to stop the adhesive from sticking back together.

Step 5
When you’re getting close to the camera assembly, just slide in the tip of the opening pick (about 4-5 mm) to keep that camera safe and sound—no smudges or damage allowed!
– Take a fourth opening pick and sneak it under the top right corner of your phone.
– Glide that pick along the top edge and slice through the adhesive like a pro.
– Leave the opening pick chilling in the top left corner to keep the adhesive from sticking together again.
Step 6
Hey there! When you’re working near the power button, remember to gently slide in just the tip of the opening pick (~3-4 mm). This way, you’ll keep those power and volume buttons safe and sound from any harm.
– Slide a fifth opening pick under the top left corner like a pro.
– Gently glide the opening pick down the left edge of the back cover to cut through the last bits of adhesive.
